PURPOSE:To shorten memory check time at a multiprocessor system. CONSTITUTION:When a system is started, CPU 11 and CPU 12 check local memories 14 and 15 which they themselves have, refer to an allocation table in ROM 18 and recognize banks which they themselves share among a common memory 16. Thus, CPU 11 checks a bank 16-1, and CPU 12 banks 16-2 and 16-3. In such a case, the respective banks are in the same size and CPU 12 has processing speed twice as much as that of CPU 11. Thus, time which both CPU require for checking the memories becomes equal, and starting processing time as the whole system is shortened. |
